Today I was playing around in Delfino Plaza and used rocket storage to fly above the map just to mess around with glitches, but I ended up falling into the Corona loading zone by mistake. I have 120 shines, but theoretically you could simply just fall into the Corona loading zone once you have 30 shines and the rocket nozzle, making Any% way shorter. I'm going to play through the beginning to try to get 30 shines to test my theory, but I thought I'd mention it.
Does anyone know why this isn't implemented yet? Is it possible the endgame just doesn't happen without getting all of the Shadow Mario shines? I'm extremely curious!
First off, you'd be better off posting this in the Sunshine forum so that someone who runs the game sees it. Second off, I don't run Sunshine but I'm pretty sure the Corona loading zone isn't loaded until you've gotten all the Shadow Mario shines.

Some games also have their own speedrunning discord sunshine included if you want to post it there instead or if you just want to talk about other things to that games runners. These forums are just for more general things that doesn't necessarily correlate to any particular game.
